How do I connect, and where do the trunk details come from?

SIP trunks for voice, SMPP binds for SMS. Details and credentials are issued automatically when you buy a route.

SIP auth

IP whitelist, or username and password.

SMS

An SMPP bind.

Credentials

Issued automatically when you buy a route.

How fast can I go live?

Minutes. Open an account, take your API key, top up, and send your first call or SMS. No sales call, no contract.

Do I have to buy a route before I can make calls?

No. You need termination, and it can come from the marketplace or from a carrier you contract yourself.

From the marketplace

Buy a listed route and send over it.

From your own carrier

List them as a private route on your own account and send over it directly. No purchase involved.

Who can see a private route

Nobody else. It cannot be seen or bought by anyone but you.

How we pick one

Your own routes and your purchases are treated exactly the same when we choose a route for a call.

Does a caller ID have to be a number I bought from you?

No. Any valid E.164 caller ID is accepted, so you can build and test the call path before buying a single number.

US voice origination

Separately requires a completed STIR/SHAKEN compliance profile.

What carriers do

They may reject caller IDs they do not recognise, so a real, reachable number performs better than an invented one.

What buying numbers is for

Giving each customer an identity and somewhere to receive calls. Not permission to dial out.

Which numbers can send and receive SMS?

The number catalogue does not flag SMS support per number yet. If you need a number for texting, ask support before you buy.

What upstream tells us

The number type only: Local, National, Mobile or Toll-free.

Why we do not infer it

A guess could have you buy a number that cannot text.

When it changes

Per-number SMS capability will appear in the catalogue rather than being inferred.

How is route quality shown?

Every route lists its ASR, ACD and PDD next to our Exchange Score, a 1-100 rating we calculate from measured traffic, so you can buy on quality as well as price.

I have my own carrier. Do I list it, or just use it?

Either, and you can do both. Same carrier, two jobs.

As a marketplace route

Listed for sale. Other buyers can purchase it, so other people’s traffic earns you money.

As a private supplier

Added on your Switch. Only your own traffic goes to it, and it just carries yours.

Who sees a supplier

Nobody. Adding a carrier as a supplier does not expose it to anyone.

Do developers pay more than carriers?

No. Both draw from the same wholesale market at the same rates - the platform fee is identical.

Can I bring my own app and bill my users through you?

Yes. Create sub-accounts for your users and set your own retail price above the wholesale rate.

Every call or message

Bills the sub-account at retail.

Your margin

Credited to you automatically.

Your users

Never see our rates.

Two operational questions come with sub-accounts: how a call is attributed to a customer, and where its SIP password comes from. Both are in troubleshooting.

Can I sell and buy at the same time?

Yes. Most operators do both: buying termination for their own app on one destination while selling their own routes on another.

Tracked separately

Balances, CDRs and margin, for each side.

Not duplicated

The same account does both, without a second login.

Prepaid balances, platform fees and settlement on delivery are set out in developer pricing.
